(Mashable) -- Here's an interesting tidbit from the Google+ stats trackers: Three quarters (or more) of Google+ users are male.

SocialStatistics, a third-party site that gathers data from select profiles, pegs the percentage of male users at 86.8%, while FindPeopleOnPlus, which curates information from about a million users, says men constitute 73.7% of Google+.

FindPeopleOnPlus also discovered that 95% of the Google+ users who say they are "looking for love" on the site are male. Some 25,000 users in their sample identify themselves as single, versus 19,000 married and 12,000 in a relationship. The vast majority of the million users sampled don't say what they are.

With around 60% of users identifying themselves as web developers or software engineers, that paints a fairly stereotypical picture of Google+'s userbase: nerdy guys who have deep understandings of technology and who don't mind killing some time setting up Circles of friends.

It's true that the early adopters of any new technology are usually male. But Google+ will have to appeal to a mainstream audience if it's to reach mass adoption anytime soon.

Consider the gender breakdown for Google+'s biggest competitor, Facebook. The social network is close to a 50-50 split between men and women. And some of Facebook's most addicted, most enthusiastic users are women.
